t25 14b
 

about how much hp will a t25 or a 14b turbo put out on a d16y7

Re: t25 14b
 

A million, numbnuts.

Quit making multiple stupid threads you ------- retard ::)

Re: t25 14b
 

t-25 is smaller than a 14b, usually maxes out around 200-ish hp. 14b can put out enough air to sustain 250 without air temps getting too high.

Re: t25 14b
 

but is it true that the t25 comes with 10psi and my pistons can only go up to 8 psi safly right.? cause i was leaning towards the 14b cause every thing i read says that they were better turbos any way. but i am just using the car as a daily driver so i only wanted around 200hp any way. and i think the 14b was 10psi also im not sure. plz coorect me if im wrong with any of this...

Re: t25 14b
 

I want to shoot you in the nuts so you don't produce retarded offspring like yourself.

Re: t25 14b
 

Wow...where are you getting your info? I'm not sure if I'm reading it right, but you're talking about the stock wastegate's being set to 10psi? Settings won't be an issue if it's properly tuned, not to mention 10psi from a t-25 will still be below the 200hp level. Max I ever saw from a t-25 on a d16 was 211hp @ 17psi tuned on a dyno with Hondata.

Re: t25 14b
 

i understand that the t25 will still give me the 200 but i was reading a thread on one of the websites not sure which one but they were saying how my motor waent strong enogh for more then 8lbs of boost if i understood it right it is a d16y7 with a few upgrabes cams pulleys clutch fuel rail and a few others. and also is it true that the 14b is a better turbo?

Re: t25 14b
 

Yes, the 14b is a much better turbo. Whoever told you your motor wasn't strong enough for over 8psi is a retard, you can even tell him I said that lol. CFM flow is much more abusive on a motor than pressure is. Think of it like this...take your motor with a 14b @ 12psi against the same motor with something much larger...say a t3/to4e (we're going to assume that it'll be properly sized for argument's sake even though it's a very bad matchup). Say that 14b combo produces 250cfm at 12psi and lands in the 80-90% efficiency range on it's compressor map (not exact numbers, just for illustration). You are putting 250cfm of cool forced air into your motor...detonation is low due to low intake temps, and timing and fuel are tuned properly. Take now the t3/to4e at ohh, say 8psi. Say that to4e produces 400cfm at that pressure. Most people would think it's safer because the psi pressure is lower right? Wrong. At 8psi that to4e is on the low side of it's efficiency range, maybe in the 60% (also not a correct number, just for illustration) range. Because it's efficiency is so low, heat temps rise dramaticly. More fuel and less timing are used, raising exhaust temps which can transfer some more heat over to the compressor side, raising temps even more, increasing chances of detonation. Detonation kills engines due to the extreme amounts of pressure created, well beyond that 12 or 14 psi mark.
All the numbers I put down here are not actual numbers though, so keep that in mind if someone thinks they're going to be funny and flame me for it...it's just to illustrate a point. Just keep in mind it's really not the psi you run, it's the cfm and where it lands in that turbo's peak efficiency range that counts. Rule of thumb is choose a suitable power goal (like 200hp) and match your turbo to that goal using the smallest possible turbo to achieve it, and tune it well. Your engine and your wallet will thank you.

Re: t25 14b
 

well 200hp was the power goal that i chose so u told me in a reply that the t 25 would just be under the 200 so if i go with the 14 b it will be right around the 200-210 hp range if tuned properly. or should i go with the t25 tuned properly since it is smaller and cheaper to the wallet. i dont mean to be a pain about this but i am acctually understanding what you are saying most of the time.

Re: t25 14b
 

Glad to hear it...most noobs don't care to hear this stuff. Since your goal is 200-210hp go with the 14b. The t-25 can do it, but it'll be stressed out pretty bad, meaning way out of it's efficiency range to do so. At that far out of efficiency it'll pretty much blow all hot air, increasing your chances of detonation. I should clarify my previous statement...choose the smallest turbo possible within the peak efficiency range for the power goal you want.
As far as the cheaper part goes, you can still grab 14b's for $100 and less.

Re: t25 14b
 

now im going with the 14b i do need to upgrade my ingestors right? and get 450cc injectors?or do i not have to.

Re: t25 14b
 

Yeah your ingestors will be far too small for the new load.

Re: t25 14b
 

4

Re: t25 14b
 

so 450cc

an also i was reading the noob thing on the top of the page and tring to figure out wht type of fuel manigment i should go with. kinda confused me all of them said they werent that good so which ones are good for my set up. with the 14b

Re: t25 14b
 

and also i dont want a water and oil cooled turbo right or it dont matter.

Re: t25 14b
 

If you're obd1 go with Crome or Uberdata. If you're obd2, convert down to obd1 and use Crome or Uberdata ;D
Doesn't matter. 14b's have both oil and water-cooled...it's a good idea to use them though, less chances of oil coking on the shaft.

Re: t25 14b
 

most turbos are both anyways, but most people only use oil cooled, not the water.

Re: t25 14b
 

how do i tell wether its obd1 or obd2?

Re: t25 14b
 

and also i found this t3

http://cgi.ebay.com/ebaymotors/91-SA...QQcmdZViewItem

wht do you think...

Re: t25 14b
 

not trying to be a dick or anything but, considering how many questions you're asking and the kind of questions you're asking, you should REALLY sit back and do some more reading on your own. Do yourself a favor, go out and buy Maximum Boost by Corky Bell. That book right there is the boost bilble! Another good place to go and research is www.d-series.org. So after you've done some more research on parts and how things work, THEN come back for more specific questions.

Re: t25 14b
 

well i have been reading a lot on d series.org this website and a bunch of other forums and by me asking some questions and a lot of them im learning alot. a month ago when i started reserching and reading i new absolutly nothing but im tryin to learn thats y when i read sumthin and dont understand it i ask u guys cause u actualy awnser the question in a understandable way. thanks i am going to go pickup that book its kinda exspensive though 40.00 at barnes and noble went there to day.

thanks guys and plz keep helpin me i just bought a t3 turbo i know that i have been leaning towards the 14b but i found this t3 for a good price. the link is above tell me wht you think

Re: t25 14b
 

Please tell me you didn't buy that turbo :l If you did, don't expect to run it anytime soon. It's been taken apart for 1, so now it needs to be at least re-balanced. #2 is that shaft looks scored to hell. The bottom line is it needs a good overhaul before you can even use it.

Re: t25 14b
 

where can you get a turbo balanced at??? I may need to do a rebuild on a turbo sometime

Re: t25 14b
 

Just contact Blaast, he's a sponser here. He can rebuild/balance your turbo and whatever else you need for it. :6

Re: t25 14b
 

Re: t25 14b
 

so whats a good fuel mangment system with obd2

Re: t25 14b
 

Getting a conversion harness to go down to obd1, and running Crome or Uberdata on a chipped ecu.

Re: t25 14b
 

i dont want to convert i live in ny wont my check engine light come on with that

Re: t25 14b
 

Thats how your engine will fail with some shitty ass nigro.com fuel management. Dont half ass your setup. Get a obd1 computer, harness and chipped p28 and have someone burn you a chip.

Or you can go with some check valves, or a fmu, and suck a random guys dick and call it a day.

Re: t25 14b
 

so if i go with an fmu what is a good one?

Re: t25 14b
 

the one that comes with a hand gun so you can kill yourself for buying an fmu....

Re: t25 14b
 

There really is no "good" fmu setup, and if you do run one you're looking at around 6psi tops safely. But since you live in NY you have limited choices...you can still do the obd1 conversion if you know the guy doing the inspection and he hooks you up, run an fmu and pass with your obd2 ecu (although when he sees a ---- load of check valves he still may not pass it), or build your kit and run it until inspection time, then put it back to 100% stock in order to pass whatever emissions if that's what you're worried about. If you don't have an emissions test, convert down to obd1 and nobody will be the wiser. And no, it won't pop a check engine light.

Re: t25 14b
 

im going to get a wastegate for 6 psi for now then when i change my internals on my motor then i will go higher i dont want to blow my motor yet. so a fmu will be safe up to that right. then when i go higher i guess i will go to obd1

Re: t25 14b
 

should i get 450 440 370cc injectors
